Assumptions:
- The 5HP motor has an efficiency of 75% (converts 75% of electrical power to mechanical power).
- The motor will run at full load (5HP) for 4 hours daily.
- The solar panels are rated at 12 volts and have a peak power output of 200 watts each.
Calculations:
1. Calculate the power consumption of the motor:
Power = (Horsepower * 746 watts/HP) / Efficiency
Power = (5 HP * 746 watts/HP) / 0.75 = 3732 watts
2. Determine the daily energy consumption:
Daily Energy = Power * Operating Hours
Daily Energy = 3732 watts * 4 hours = 14,928 watt-hours (Wh)
3. Calculate the number of solar panels required:
Peak Sun Hours: Let's assume your location receives 5 peak sun hours per day. Peak sun hours represent the approximate number of hours when the sun's power output is at its maximum.
Required Panel Wattage = Daily Energy Consumption / Peak Sun Hours
Required Panel Wattage = 14,928 Wh / 5 hours = 2,986 watts
4. Determine the number of 12-volt, 200-watt solar panels:
Number of Panels = Required Panel Wattage / Solar Panel Wattage
Number of Panels = 2,986 watts / 200 watts ≈ 15 panels
Therefore, based on these assumptions and estimations, you would need around 15 x 12-volt, 200-watt solar panels to run a 5HP motor for 4 hours daily, assuming optimal sun exposure and battery storage.
Remember that these calculations are based on specific assumptions, and the actual requirements might vary depending on your unique setup. It's advisable to consult with a qualified solar professional to perform accurate calculations based on your specific needs and location.
